This section groups together both Lambdomas and Diamonds with the latter term used by Harry Partch to describe his particular lambdoma. Strategies to fill out the gaps left by the lamdoma are shown in Partch's case and could be applied to other like structures. Novaro in 1927 conceived of a lambdoma and filled like gaps in a 7 limit diamond but mapped his structures in a way that shows the tie with the Farey series, Pascal's triangle, and the co-prime grid.
